Probiotic and enzymatic formula that maximizes the benefits of every gram of protein you consume*
Protein Optimizer works along the gut-muscle axis to improve protein digestion and the absorption of amino acids, promoting muscle recovery and digestive comfort.* NSF Certified for Sport®
Consuming enough protein is essential for muscle recovery, performance, and overall health – but adding protein to your meals is only part of the equation. To get the full benefit, your body needs to efficiently digest the protein you consume, absorb its amino acids, and utilize those nutrients where they’re needed most.
Protein Optimizer is designed to support this process through the gut-muscle axis – the connection between gastrointestinal (GI) health, nutrient absorption, and muscle function – with a targeted formula that combines Mycohsa™, a probiotic blend with digestive enzyme support, and Bacillus coagulans SNZ 1969®, a clinically studied probiotic strain.
Together, these ingredients promote healthy digestion, support microbiome balance, and enhance the absorption of nutrients that help build lean muscle mass.*
